  • the vehicle 12 comprises a frame structure 13 having wheels 14 (only one wheel is shown in this disclosure) suitably rotatably mounted thereon, and the wheels 14 are adapted to roll on a conventional track 15.
  • An axle 16 extends between and is fixed to an associated pair of wheels 14 of the vehicle 12 for rotation therewith as the vehicle 12 moves along the track 15 in the usual manner, and the axle 16 serves as a rotatable driver shaft for imparting rotary motion to the generator 11.

  • a threaded set screw 31 is employed to detachably fix the sheave 30 to the shaft 22 with the set screw 31 being threaded through a threaded opening in a flange 32 of the sheave 30 and having a terminal end which engages the flattened surface 23 of shaft 22 to assure the sheave 30 will not rotate relative to the shaft 22.
  • other means may be employed to detachably fix the sheave 30 to the shaft 22.
  • a nut and flat washer may be used on a shaft 22 having a threaded end portion and with such shaft and sheave being provided with cooperating keyways and a key.
  • the apparatus 10 employs belt means shown as a plurality of two endless power transmission belts each designated generally by the reference numeral 33 and such belts are operatively connected between the driver sheave 24 and the driven sheave 30.
  • the apparatus 10 also has means yieldingly moving the generator 11 about its pivot support means 27 and such means yieldingly moving is designated generally by the reference numeral 34; and, the means 34 moves the generator 11 and thus driven sheave 30 away from the driver sheave 24 thereby placing a substantially constant yielding tension on the belts 33 to assure that the driven sheave 30 and generator are driven in an optimum manner without or free of excessive loads on the belts 33.
  • the apparatus 10 comprises a telescoping member 35 which has the previously mentioned pivot support means 27 provided at its outer end.
  • the member 35 is adapted to be received in telescoping relation within the frame structure 13 and in particular an inner portion 36 of the member 35 is adapted to be received in an elongate opening 37 in the frame structure 13.
  • the opening 37 is of rectangular peripheral outline and it will be seen that the member 35 has a plurality of cylindrical bores or passages 40 provided in its inner portion 36 and the bores 40 are disposed in parallel spaced relation transverse the longitudinal axis of member 35.
  • Each bore 40 is adapted to be aligned with a pair of axially aligned openings 41 provided in the frame structure 13 and a pin 42 is adapted to be inserted therethrough whereby member 35 may be telescoped to a plurality of positions.
  • the telescoping member 35 has a bifurcate end defined by a pair of spaced parallel legs 43 and the generator 11 has lug means shown herein as a pair of spaced parallel lugs 44 extending from the housing 20. It will be appreciated that only a single lug 44 may be provided as will be described subsequently.
  • the lugs 44 are defined as an integral part of housing 20 and may be integrally defined in such housing so that the housing and lugs comprise a single-piece structure.
  • the lugs 44 have opening means therein defined by an opening 45 in each lug 44 and the openings 45 are disposed in axially aligned relation with a common central axis through openings 45 being disposed parallel to the generator shaft 22.
  • the legs 43 defining the bifurcate end of the telescoping member 35 have coaxially aligned openings 46 therein and the pivot support means 27 has a pin 47 which is adapted to extend through the openings 45 and 46 and support the housing 20 on the telescoping member 35.
  • the pin 47 engages cylindrical surfaces of the lugs 44 and arms 43 which define openings 45 and 46 respectively and thereby support the generator 11 in a pendulum-like or suspended relation at the terminal outer end of the telescoping member 35.
  • Each of the sheaves 24 and 30 has a corresponding plurality of annular grooves therein and in this example the sheave 24 has a plurality of two grooves 50 defined therein while the sheave 30 also has a plurality of two grooves 51.
  • Each groove 50 and 51 is defined by symmetrically disposed radially outwardly diverging side surfaces interconnected at the bottom edges thereof by a right circular cylindrical surface and as is well known in the art; the grooves 50 and 51 are particularly adapted to receive endless belts 33 therein with the belts 33 being of trapezoidal cross-sectional outline whereby such belts are in the form of so-called V-belts.
  • the V-belts 33 may be made of any suitable material known in the art, are of known construction, and are preferably made of elastomeric materials provided with reinforcement, as desired.
  • the apparatus 10 has the means yieldingly moving the generator and as previously mentioned such means is designated by the reference numeral 34.
  • the means 34 is preferably in the form of torsion spring means and in particular is in the form of mechanical torsion spring which is designated by the reference numeral 53.
  • the torsion spring 53 has one end portion 54 engaging an integral web structure 55 of housing 20 disposed between lugs 44 and an opposite end 56 engaging the telescoping member 35 so as to impart a substantially constant yielding force against the housing 20 of the generator 11 and thereby provide a substantially constant tension in the V-belts 33.
  • the torsion spring 53 of this example imparts a force on the generator 11 which tends to rotate same counter-clockwise as viewed in FIG. 2.
  • a plurality of two belts 33 are shown operatively connected between the sheaves 24 and 30; however, it will be appreciated that any desired number of belts may be employed and the required grooves provided in the driver sheave and driven sheave. For example, only one belt may be employed or more than two belts may be employed.
  • belts other than V-belts may be used; however, regardless of the type belt used the drive apparatus of this invention assures that belts thereof operate under substantially constant yielding tension whereby such belts operate with optimum efficiency.
  • the spaced lugs 44 have a dimension across their outside surfaces which is measured parallel to the axis of the pin 47 which is less than the corresponding dimension between the inside surfaces of the arms 43.
  • This enables controlled thickness washers 57 to be used between one or both of such outside surfaces and the inside surfaces of one or both arms 43 and around shaft 43 to position the lugs 44 along pin 47 whereby sheave 30 may be aligned with its grooves in the same planes as the grooves of sheave 24.
  • the controlled thickness washers 57 comprise adjusting means of the adjustable pivot support means 27 enabling alignment of the generator and its driven sheave with the driver sheave.
  • a single central lug 44 of substantial axial thickness may also be provided on housing 20, instead of the two lugs 44, and by disposing controlled thickness annular washers 57 on the pin 47 on opposite sides of the central lug and using a modified torsion spring, i.e., a spring of less axial height measured parallel to the axis of pin 47, the generator 11 may be positioned by sliding its lug along pin 47 within predetermined limits of sliding so that the sheave 30 is precisely aligned with sheave 24 and the belts 33 operate in an untwisted manner in a pair of parallel planes.
  • a modified torsion spring i.e., a spring of less axial height measured parallel to the axis of pin 47
  • the drive apparatus 10A in FIG. 3 instead of having a telescoping member supporting its pivot support means 27A has a U-shaped bracket 60A defined by a bight 61A and a pair of spaced parallel legs which extend from opposite ends of the bight 61A and such legs are designated by the reference numeral 43A and will also be referred to as arms 43A.
  • the elongated slot 63A allows movement of the U-shaped bracket 60A on the frame structure 13 and such slot 63A cooperates with washers 57A to enable the sheave 30A to be precisely aligned with its driver sheave 24A (not shown) so that the belts 33A operate in their sheaves in an untwisted manner and in a pair of parallel planes.
  • the slot 63A, bolt 62A, and washers 57A comprise the adjusting means of the adjustable pivot support means.
  • the bracket 60A may also be cast as an integral part of the frame structure 13A.
  • the bracket 60A instead of being fixed in position by a threaded bolt may be fixed in position by any other suitable means such as welding in position after precisely aligning such bracket so that the sheave 30A is precisely aligned (in the manner previously mentioned) with its driver sheave.
  • the apparatus 10A also is shown employing a torsion spring 53A; however, other embodiments of the spring means may be employed as will be discussed subsequently.
